Beloved Lilies

easter-lily-poisoning

Beloved plant is toxic to house pets

The rules for calculating Easter are rather complex. Easter Day falls on the first Sunday after the first full moon that falls on or after March 21, but the “full moon” referred to is not the real moon but a theoretical moon that doesn’t quite match the one in the sky. In 1928, the British House of Commons agreed to a bill fixing the date of Easter, subject to agreement by various Christian churches. Efforts to secure that agreement, however, have been going on ever since.

The name of “Easter” is generally believed to be derived from Eostre, the pagan goddess of dawn, though recent research suggests that Eostre may not have been a goddess at all but the name of a season, and the “goddess” was only a mistranslation by the Venerable Bede in the eighth century.

Easter Island in the Pacific was discovered by the Dutch sailor Jacob Roggeveen on Easter Day 1722.

The plant that we now call an Easter Lily was discovered in 1777 in the Ryukyu Islands of Japan. Interestingly, though, the white lily is mentioned in the Bible and has been a symbol of Christianity since its beginnings.

If you’ve been gifted with an Easter lily and you have pets, you should know that the plant is poisonous. Though the plant presents a high rate of toxicity to cats who ingest it, many pet owners are not aware of the dangers posed by it. There are no documented cases of poisoning by Easter lily in dogs, but there is a definite possibility of effects such as gastrointestinal upset or internal obstruction if your dog eats a large amount of this plant. Most cases of ingestion of the Easter lily by canines will mean mild gastrointestinal upset simply because the digestive systems of dogs are not used to processing plant material, especially in large quantities. While considered as lethal to cats, the Easter lily is not toxic to dogs but this does not mean your canine companion should have free rein to ingest this plant. The Easter lily is known to be extremely toxic to the feline species. While this flower is not documented as poisonous to dogs, ingestion of the flower in large quantities may  lead to digestive discomfort.

Repotting Hibiscus

Raise your hands: who put their hibiscus plant outdoors for the summer and now it’s looking pretty sick with dropping leaves all over your floor?

It is probably a case of too little water, but increasing your watering schedule is not going to help. A hibiscus grows quickly during the summer, and the increased root mass displaces the soil in the container. The water — as well as the fertilizer you probably applied religiously every two weeks — is traveling straight through rather than soaking in. You pour water in, see it come out through the drain holes, and naturally assume that the hibiscus has been watered and fed. Unfortunately, the soil around the roots remains dry, and the plant remains thirsty.

Knock the hibiscus out of its pot and take a look. Overcrowded roots signal that moving to a larger container is necessary. When repotting, score the root ball with a knife or pull through the roots with a hand cultivator and tease some away so that they will grow into the fresh medium. If you don’t, the roots will remain would tightly, occupying the center of the container, and you’ll have the same starved, thirsty plant — just in a larger pot.

Of course, no matter what you do, a hibiscus will probably sulk in the winter. It is a full-sun tropical plant, and the low light, short days, and low humidity that come with spending a Northern winter indoors are even more depressing for it than for us.

One further note that may fall under the horticultural truth-in-packaging principle: small potted hibiscus, frequently sold in the spring, appear to be dwarf plants covered with large flowers. Most, however, are treated with a growth retardant to keep them small. When the retardant wears off after a month or two, the 2-foot plant is on its way to becoming a 6-footer. This can be disconcerting to anyone who has not seen the same phenomenon occur in a teenage boy.

Home Alone

House-Plants-All-My-Favorite-Low-Maintance-House-Plants-5As the holidays are coming to an end, and the cold weather sets in, many of us are looking forward to getting away to warmer temperatures for a while. But, what about your houseplants while you’re gone?! Only a plant-savvy human being can give an assortment of houseplants the different amounts of water they’re likely to need while they are home alone. But it isn’t always easy to find a willing plant sitter, and it’s even harder to find one who not only means well but has houseplant skills (returning to find that two-thirds of one’s little green children have drowned is no better than finding them dried to a crisp). So if you must leave them unattended, the following steps should keep them alive — if not happy — for up to a month.

  1. One at a time, bring the plants into very bright light and check them over top to bottom for pests and diseases. Don’t forget to look under the leaves and against the stems where they enter the soil. Problems that are very small now can balloon in your absence, and since the plants will be grouped together, those problems are likely to spread. Any afflicted plants should be treated and, for good measure, kept quarantined in a room of their own while you’re gone.
  2. Decide on a water-delivery system, ideally one that is triggered by the plant itself. Like the overzealous friend, timer-driven waterers usually deliver more than the plants need. Garden-supply stores and catalogs sell an assortment of capillary mats and water wicks that are less likely to drown plants, or you can go the low-tech route and opt for just supplying humidity (put the plants in plastic dish tubs lined with deep layers of pebbles or styrofoam peanuts and shallow layers of water.
  3. Set up the system where the plants will stay cool and get only a small amount of light. The bathroom is probably the best place since it is usually both cool and dark, and is the room best protected against water damage. If the plants will all fit in the tub, plan to put them there. Don’t draw the shower curtain unless the room is very bright.
  4. Water everything thoroughly. Soak clay pots until saturated; bottom-water plants in plastic pots until soil at the surface is wet. Let excess water drain, then group plants closely but not tightly — there must be a bit of air circulation or they’ll all get fungus diseases.
  5. Speak to them lovingly and close the door. They’ll be fine.

Bringing Hibiscus Indoors

Over-wintering large, flowering tropical plants like Hibiscus rosa-sinensis is always a challenge. They never thrive in the living room the way they do outdoors. Leaves turn yellow and drop, flowers seldom appear. Assorted pests do appear — in droves. No wonder gardeners dream of exiling these shrubs to the basement, where they can be out of sight and out of mind until spring.

This kind of hibiscus never sleeps, however, and trying to store yours as though it were dormant may give you a rude awakening. If you want to try it anyway, keep the plants cool, 45º to 50ºF. Expect them to drop all their leaves. They will likely get bugs. And they will still need to be brought into light well before summer planting time.

A better choice is a room that gets lots of light and is cool enough to slow growth, 60º to 65º. If you must put hibiscus plants in the living room, keep them in the sunniest place, away from direct heat and far enough from the window so they don’t suffer big temperature swings from night to day. There is no point in misting, but if you don’t have a humidifier this would be a good excuse to get one. Keep the soil barely but consistently moist, and don’t feed unless flowers appear. Watch out for aphids, whiteflies, and red spider mites. If you see them, treat promptly with insecticidal soap.

Hibiscus is tough. The plants will not be glorious inside, but they will survive. Cut them back in late April, removing leggy branches and working to create a pleasing shape. New growth should start almost at once. It is tempting to set the plants out as soon as the danger of frost is past, but hibiscus is a heat lover that will be happier inside until it is warm out day and night — late May or early June.

Alternatively, treat hibiscus as an annual indulgence. While they are still beautiful, give your plants to somebody with big windows and no qualms about getting rid of ailing ornamentals. Enjoy a carefree winter, and get new ones next year.

Houseplant Survival Guide

by Diana Alfuth, horticulture educator for Pierce and St. Croix counties UW-Extension

Houseplants-GettyImages-72195187-59d3a98b519de20012d7af62January and February are probably your houseplants’ worst months. While we northern Wisconsinites dream of a winter vacation in warm, sunny places, your houseplants can only sit and wait for better conditions to come to them. Winter’s short days, low light levels, and dry air are hard on houseplants. And, by now your plants’ leaves may have accumulated dust and your windows may be in need of washing. Dirty windows block even more light.

To help your plants make it through their worst winter months, inspect and treat plants for any insects, such as mealybugs, scale, or aphids that may have appeared. Clean off any accumulated dust by wiping each individual leaf with a damp cloth or giving them a shower. Small plants can be washed in the kitchen sink with a sink sprayer. Large plants can go in your shower. I recommend covering the soil surface with aluminum foil to prevent the potting mix from splashing out or getting waterlogged.

Next, wash your windows inside and out. Even though it’s cold outside, when the sun hits the window you can wash the outside without your cleaning solution freezing.

If your plants are looking stressed with sparse or light-colored foliage, try adding supplemental light. Even a table lamp with a fluorescent bulb above the plant can add extra light to get your plant through winter in better shape.

Normally, you do not want to fertilize houseplants from October through January because with low light levels, plants will not be growing. Fertilizers can build up in the soil and damage roots, or they can force plants into spindly, weak growth. But by the end of February, with the days getting longer and the sun getting higher and stronger, pinch back leggy growth and give your plants their first fertilizer of the year to help them put on new, vigorous growth.
